Each culture has its own halvah, united only by nameâwhich derives from the Arabic word for âsweetââand the fact that each is a sweetened candy or dessert, often an ancient and beloved recipe. A trip to Israel is not complete without sampling the countryâs halvah.
The amount of vitamin D you get from exposing your bare skin to the sun depends on: 1  The time of day â your skin produces more vitamin D if you expose it during the middle of the day. 2  Where you live â the closer to the equator you live, the easier it is for you to produce vitamin D from sunlight all year round.
Adequate vitamin D intake is important for the regulation of calcium and phosphorus absorption, maintenance of healthy bones and teeth, and is suggested to supply a protective effect against multiple diseases and conditions such as cancer, type 1 diabetes and multiple sclerosis. A fair-skinned person with full body exposure to the sun can synthesize up to 20,000 IU of vitamin D3 in 20 minutes. 2  Vitamin D deficiency is common, especially in the elderly, infants, people with dark skin and people living at higher latitudes or who get little sun exposure.
